ManiFausto

(n.) a public declaration, written in blood, sweat, tears
and sometimes sexual fluids, of an esoteric and heretical
nature, in which an individual or group sell their soul(s)
into the bondage of a particular political or artistic
theory or policy (and in the case of swaying from said
ideology go to hell and are punished by the devil).
Example:
The Neo Pagan Anarchist Nihiistic Marxist organization
wrote their ManiFausto in blood. When Syd left the group to
become a Born Again Christian, he renounced his former
convictions. The Devil promptly appeared, taking him to
hell, where his soul, forever in torment, burned amidst the
sulphur and brimstone. He always regretted having signed
that damn ManiFausto.
